Digital Elevation Model Hamburg DGM 1

Derived, area-wide digital terrain model with a grid width of 1 meter. In 2020, laser scanning measurements (airborne laser scanning) were carried out for the area of ​​the Free and Hanseatic City of Hamburg (excluding the area of ​​the Hamburg Wadden Sea). The data are available in position status 310 (ETRS89/UTM), with altitude information above mean sea level (NHN), according to DE_DHHN2016_NH. The accuracy of a single measuring point is approx. ± 15 cm in clearly defined areas, such as on street surfaces. The accuracy is lower in areas of shading (bridges), vegetation, especially areas in forest and shrub areas and on steeply sloping terrain. The LGV offers the following grid widths as standard: DGM 1 (grid width 1m), DGM 10 (grid width 10m), DGM 25 (grid width 25m). An annual update of this data takes place via aerial photography. In addition to the pure provision of height information as a regular grid, the data is also provided as a service in a triangular mesh (TIN). Data exchange with 2D and 3D CAD systems is ensured. As a further service, e.g. contour lines and profiles can be derived or volumes and inclinations can be calculated. By integrating further basic geospatial and technical data (vector and raster data), further services can be derived, e.g. for the areas of water management, civil engineering, environment and urban planning as well as energy supply large and small-scale applications.
